[QUOTE="WayneF, post: 387306, member: 12496"] That is my belief, but it is more just an assumption. The diameter change we see looking in the front during zoom is clearly just an optical magnification view. There are zooms that do offer constant max aperture regardless of zoom, which is much harder. :) The design of the variable max aperture lenses is less expensive, they don't have to worry with the aperture diameter.
